What are GBIF and OBIS?



GBIF and OBIS are international initiatives that aim to provide open access to biodiversity occurrence data.


Although they are most well-known for their publishing platforms, and their role as data aggregators…


…both initiatives represent an investment from the international political community and a vibrant scientific community of nodes, publishers, and users of standards and practices.

What are GBIF-US and OBIS-USA?

USGS-SAS Biogeographic Science Branch manages the US nodes: GBIF-US and OBIS-USA.

  • represent US interests in the international initiatives
  • advise the US scientific community on biodiversity informatics, data, and standards
  • mobilize and synthesize data to enhance its FAIRness and relevance on national and international scales.

We also manage the OBIS-USA and GBIF-US Integrated Publishing Toolkits (IPTs)!

Why do we work with GBIF and OBIS?

https://ark.digitalcommonwealth.org/ark:/50959/r781wg156

Sparkly fountains need robust plumbing systems.
- Terry McConnell (International Digital Twins of the Ocean Summit 2022)

The US has been a voting participant in GBIF since 2001 and became an OBIS-USA node in 2005.


The USGS is shepherding over two decades of investment in the robust plumbing needed for national and global biodiversity science and data.

How are GBIF and OBIS the same?

Both are active and energetic communities that develop, maintain, and promote standards and practices for biodiversity science and have been doing so for > 20 years

Both promote open data and science, and publish massive amounts of standardized biological observations through their platforms

Have signed a letter of agreement in recognition that their respective communities will benefit from more streamlined ways of working together. A stronger action plan is forthcoming.

GBIF and OBIS are built on the same data and metadata standards, and share open-source tools

Important Differences

GBIF has a global scope. OBIS includes marine occurrences only.

GBIF is funded by individual participant countries. We fund GBIF-US through the NSF. OBIS is funded by UNESCO, an agency of the United Nations.

GBIF-US and OBIS-USA are unusual in that both nodes are managed by the same people.

How does it work?

This is an illustration of the GBIF workflow. The OBIS workflow is similar.

What do GBIF and OBIS do well?

  • Coordinate and serve interoperable observations of biological occurrence
  • Promote and catalyze progress for open science and FAIR data
  • Searching data at the occurrence level
  • Track data use and citations
  • Well designed tools and guidance exist for self-publishing
  • Active and diverse community

So, why use GBIF and OBIS?

Off-the-shelf platforms for publishing and tracking use of biological occurrence data with minimal financial or staffing investment. USGS, and SpringerNature, accept GBIF as an archival repository, publishing to OBIS-USA satisfies NOAA archiving requirements.

Sustainablity - International

Both organizations rely on regular international investment for funding.

OBIS recently transitioned from a project to a program, which means it now receives core UNESCO/IOC funding and staff support to enable the activity to operate on a permanent basis.

Open standards and science means that migration of data would be relatively simple in the event of a surprise shutdown.

Sustainablity - US

GBIF-US is funded by NSF (~ $600k / year). There is a US Delegation that guides GBIF for US interests.

OBIS-USA is funded through US participation in UN and UNESCO.

For operation of both nodes, USGS funds the node staff salary + travel. NOAA IOOS also contributes staff.

Both IPTs could easily transition to other management and continue to operate without US funding

Both secretariats have funding and training in place for new nodes and node managers

Things in Development

  • Taxonomic alignment

  • Facilitating round tripping of data, taxonomic updates

  • Sequence searches

  • eDNA publishing tools for non-technical / small-to-medium publishers

  • Expansion of US node staff

DNA-Derived Data

https://docs.gbif.org/publishing-dna-derived-data/img/web/sampling-processes.en.svg

Two Standards

  1. Darwin Core (DwC): Describe your biological observation.
  2. Ecological Metadata Language (EML): Describe your dataset.

The Darwin Core Archive (DwC-A)

The DNADerivedData extension

The DNADerivedData extension extends occurrence data with molecular biology metadata.

It mostly consists of terms from:

  • GGBN Data Standard
  • GSC MIxS (Minimum Information about any (X) Sequence)
  • MIQE (The Minimum Information for Publication of Quantitative Real-Time PCR Experiments).

Guidance is available: Publishing DNA-derived data through biodiversity data platforms. The guide handles barcoding, metabarcoding, metagenomics and qPCR/ddPCR.
